• Marui-compatible – designed for standard Tokyo Marui AEG gearboxes and variants

Real-World Use Cases

Whether you’re a target shooter fine-tuning a DMR build, a skirmisher looking to tighten your groups at 30m+, or an enthusiast upgrading a GBB platform, a quality tightbore barrel is a core internal upgrade. The ZCI 6.02mm bore sits between standard 6.03mm and ultra-tight 6.01mm options, offering a practical balance between performance and ease of BB feeding.

Compatibility & Upgrades

This barrel is designed for standard Tokyo Marui-spec gearboxes and compatible clones. Verify your AEG’s gearbox model and barrel length before purchase. Pair with a quality hop rubber and nub for best results – the barrel alone won’t optimise performance without complementary tuning.
